OK, knew about -B but was hoping to just be able to override cc1, which it
doesn't sound like I can do.

In case anyone was curious on "what" I was wanting this for. Was looking
for a simple way of comparing output (code gen or dumps) between two (or
more) versions of cc1 built off the same code base with individual tweaks
here and there. Currently going at it by just shuffling "cc1.versionN" into
the normal "cc1" location and getting what I want, then shuffling in the
next "cc1.versionM" in...
